It looks like Jennifer Aniston is getting the message about romantic comedies. She’s signed on for an edgier role in a new comic murder movie, “Horrible Bosses,” as a sex-obsessed dentist. According to Life & Style, it will be Aniston’s raunchiest role yet. Her character breaks a nail while pleasuring herself, compliments a man on his privates and admits she’s into kinky sex. The picture also stars Colin Farrell, Jamie Foxx and Jason Bateman and is “a total departure from the other comedies she’s been doing.”
